Abstract: PROBLEM TO BE SOLVED: To provide a flocculating and settling vessel with which the overloading state is easily eliminated and a slurry is treated with high efficiency in the case the load on the rotation of scraping blades is increased by an increase in the deposited amt. of flocs. SOLUTION: Solid materials are flocculated and settled from the slurry S housed in a vessel body. The flocculated and settled materials Sa are scraped by the many scraping members 9 mounted at a rotary supporting body 8 which is rotatable in both forward and backward directions. The scraping members 9 act to scrap the settled and flocculated materials Sa by having a prescribed angle with this rotary supporting body 8 at the time the rotary supporting body 8 rotates in the forward direction. On the other hand, the scraping members are supported rotatably by the rotary supporting body 8 in such a manner that the members rotate in the direction where the resistance received from the settled and flocculated materials Sa decreases at the time the rotary supporting body 8 rotates in the backward direction.
